METAL RAILROAD TIE.

Application filedJune 16, 1927. Serial No. 199,289.

My invention is an improvement in metal railroad ties and relates moreespecially to that type in which the tie is-formed from a rail,preferably a T-rail, bent upon itself at its ends to provide loopportions for increas ing the bearing of the tie in the roadbed andhaving wooden blocks seated in the loop portions to rest upon theinwardly projecting base flanges and provide resilient seats andinsulation for the rails as well as the means for securing the rails tothe tie by means of the usual spikes.

The principal object of my invention is to provide a metal railroad tieof this general type which is of a particular construction to increasethe stability of the tie without n1a terially adding to the weight ofthe same, and in connection with the improved form of metal tie I employa wooden block at each end thereof which ismore securely held in placeand more effective in insulating the rails from the metal tie.

\Vith these principal objects in view my invention consists in forming ametal railroad tie from a T-rail having a reinforcing flange at theupper end of the upstanding portion thereof, said reinforcing flange extending inwardly with respect to the bent end portions or end loops ofthe tie for oooperation with a particular form of wooden block seated inthe end loops and extending above the tie to receive the rails, in thepresent instance the wooden block cooperating with the end loop of themetal tie to have sntlicient bearing thereon for firmly supporting therails and insulating them from the metal tie; all'as hereinafter fullydescribed and particularly set forth in the appended claims.

In the accompanying drawings:

Fig. 2 is an enlarged plan view of an end portion of the tie, the blockbeing removed.

My invention is carried out in connection with that particular type ofmetal railroad tie in which a metal bar or T-rail 10 is bent upon itselfat its ends to form loops 11 for increasing the hold of the tie in theroadhed and provide the required bearingfor the railroad-rails supportedeither directly thereon or on wooden blocks seated in the loops on thebase flanges; but in the present instance the upstanding portion 10 ofthe T- rail or tic, which rises from the opposite base flanges 10 10, isprovided at its upper edge with a laterally projecting flange 12 for thep urposc of increasing the rigidity of the tie and more particularly tocooperate with the blocks hereinafter described upon which the rails 13are supported. In bending the end portions of the rail to form the loops11 the aforesaid flange 12 projecting at one side of the upstandingportion 10 of the T'rail or T-beam 10 is disposed at the inner side ofthe loop or bet-ween the opposite parallel members thereof. i

To more effectually support the rails 13 on the bent ends or loopportions ofthe metal tie hereinbefore described I provide a particularform of wooden block 15, shown in detail in Fig. 5, which closely fitswithin the loop portion 11 between the upright members thereofand restson the adjoining inner base flanges 1O 10, said block having a groove 16around the side of thesame to receive the inwardly projecting flange 12and having the upper portion 15 thereof extended laterally to overlapthetop of the tie including the flange 12, whereby the block not onlyhas a bearing on the base flanges but also bears on the upper surface ofthe tie to provide an additional hearing as well as more effectuallyinsulate the railroad rails from the metal tie.- The tie is secured inplace by bolt 17.

The railroad rails 13 are supported on the blocks 15, with a plate 18interposed be tween the rail and block, and are secured in place bymeans of the usual spikes 19.

Instead of having the block 15 extend all the way into the loop portionof the metal tie, as shown in Figs. 1, 4 and 6, I may use a shorterblock, 20, as illustrated in Fig. 8, and of course in this instance theblock is held in place by one or more bolts, the important feature ofboth forms of blocks being to have the upper portion thereof above themetal tie extend over the top of the rail for the purposes hereinbeforeex plained.

From the foregoing description in connection with the accompanyingdrawings it will be obvious that I provide a metal railroad tie having awooden support for the rails to give the desired resiliency and properlyinsulate the railroad rails from the metal tie. the particular form ofblock employed to serve these purpo:e.\ being securely locked in placeagainst vertical movement as well as providing a wide bearing for therailroad rails thereon.

It will he umlm'stood that the blocks are set in place by sliding themlongitudinally into the loop portions 11 ot the tie from the inner endot said loops. and as they are locked. in place by the flange. 12engaging the groove 16 only a single bolt is required tor holding themin place. The metal plates 18 reduce the wear on the blocks resultingfrom the rolling stock pasaing over the rails. and of course at any timea block may be readily replaced at little expeme. the main portion ofthe tie being of metal and therefore very durable.

I elaim:

1. In combination with a metal railroad tie having loops at its ends andbase flanges within the loops. of a hloclc for the loop end of the tiefitting hetween the side members of the loop and having laterallyprojecting upper end portions overlying the upper edge of: the bodyportion of the tie.

In combination with a metal railroad tie having loops at. itsv ends andha e flanges within the loops. of a bloel; for the loop end of the tiefitting in the loop agaiiol the curved portion thereof and enlargedlaterally atv its upper portion to overlie the upper edges of the sidemembers of the loop.

3. In combination with a metal railroad tie having loops at: its endsand base flanges within the loops. ot' a reinforcing lateral flange atthe upper edge of the body portion of the tie. and a wooden block forthe loop of the tie having a groove in ita sides to receive thereinforcing tlange at the upper edge of the tie and having its upperportion projecting laterally over the upper edge of the tie to seat onsaid flange in addition to the seating of the block on the base flange.
